Implementation of Wireless Hotspot Access Control Gateway

With the development of advanced technology and manufacturing, microprocessor had become smaller and more efficacy. For this reason, more and more embedded systems appear in our daily life, such as mobile devices and hotspots. Living with these embedded system device really bring us a lot of convenient and rapid information in time. For example, we can use cell phone to make contact with other people, via PDA to get rich stocks information from Internet, and by meteorological sensors help we could know what the weather oncoming. Since embedded system have become more and more important, learn how to develop on it would be necessary.

Wireless LANs (WLAN) extensively been used by people with mobile device or laptop nowadays. Therefore stores providing wireless network service is becoming very often. Using common wireless gateway to provide service will be a good choice because of low cost and ease to construct. However, without user authentication and management, the quality of service will become extremely awful.

In this thesis we will describe how to develop particular functions in embedded system which with modern architecture, and implement a wireless hotspot access control gateway under the WNOC total solution, to provide a wonderful WLAN environment for every wireless network user.
